FEED-WATER REGULATOR.

Specification of Letters Patent.

Patented Sept. 19, 1905.

To all whom, it 777/6Ly concern:

Be it known that we, J AOOB N. SPANABEL and LYMAN P. J USTISON, citizensof the United States of America, residing at East Palestine, in thecounty of Oolumbiana and State of Ohio, have invented certain new anduseful Improvements in Feed-Water Regulators, of'which the following isa specification, reference being had therein to the accompanyingdrawings.

This invention relates to certain new and useful improvements infeed-water regulators, and has for its object to provide a device whichcan be readily attached to a boiler to govern and regulate the quantityof water to be fed to the boiler.

Another object of our invention is to provide a device which whileparticularly adapted for controlling the inlet of water to the boiler iscapable of designating the quantity of water within theboiler; and tothis end we have provided novel means in connection with our improveddevice for adjusting the regulating and governing features of ourimproved device.

The device aims to govern the amount of water admitted to the boiler andto regulate the same, whereby an excess of water will be prevented fromentering the boiler, and consequently reducing to a minimum theconsumption of fuel in respect to the quantity of water being heated.The device also reduces to a minimum the quantity of water necessary tooperate a boiler, and increases the steamgenerating power of the boiler,owing to the fact that no excess amount of water is permitted toaccumulate Within the boiler.

With the above and other objects in view the invention consists in thenovel construction, combination, and arrangement of parts, which will behereinafter more fully described, and then specifically pointed out inthe claim, and, referring to the drawings accompanying this application,like numerals of reference designate corresponding parts throughout theseveral views, in which Figure 1 is a front elevation ofour improveddevice as connected to a boiler. Fig. 2 is a side elevation of a portionof the device used for controlling the water-inlet of a boiler. Fig. 3is a detail view of a flexible joint used in connection with ourimproved device; and Fig. 4c is a side elevation view, partly insection, of an adjustment construction used in connection with ourimproved device.

To put our invention into "practice and to demonstrate the use of ourimproved device in connection with a boiler, we have illustrateddiagrammatically the front end of a boiler, which is designated by thereferencenumeral 1, and the front or the housing of the boiler isdesignated by the reference-numeral 2. Adjacent to the boiler we mount aframework 3, having a platform 4:, and in said frame is mounted a tank5, the framework serving as vertical guidewaysfor the tank 5.

The framework and the tank are preferably mounted in horizontalalinement with the water-line 6 of the boiler 1, and the top of saidtank is provided with a pipe 7 and the bottom of said tank is providedwith a pipe 8, said pipes passing through the platform 4. and the top ofthe framework 3 and serving as guides for the tank 5. The tank 5 issupported upon the platform 4 by a coiled spring 9, which surrounds thepipe 8, and said coiled spring rests upon a plate 10, which is adjustedvertically by set-screws 11 11, carried by the platform 1. The tank 5 isprovided with a waterglass 12, whereby the contents of the tank can beobserved from the exterior thereof.

The reference-numeral 14 designates a water-inlet pipe, which isconnected by a pipe 15 to the boiler 1, and the pipe 1 1 is providedwith a valve 16, having a vertically-actuated valve-stem 17. The pipe 14is provided with a split sleeve 18, carrying a standard 19, to which ispivotally connected, as indicated at 20, a lever 21. The lever 21 isconnected to the vertically-actuated valve-stem 17, as indicated at 22,and the forward end of the lever 21 is adjustably secured between twonuts 23 upon a screw-threaded stem 2 1. The screwthreaded stem 24: issupported by a T connection 25, carried by the pipe 7 of the tank 5.Upon the opposite side of the boiler is mounted the ordinary type ofWater-gage 26,

which is connected by a pipe 27 to the T connection 25, and also by apipe 28 to the swiveled joint 29. An auxiliary pipe 30 connects the pipe28 with the boiler 1. A pipe 31 connects the pipe 8 with the swiveledconnection 29.

The operation of our improved feed-Water regulator is as follows: Wateris admitted to the boiler 1 through the pipe 14, valve 16, and pipe 15,and as the water enters the boiler 1 and rises therein it simultaneouslyrises in the tank 5 and the water-gage 26, on account of said tank andwater-gage being connected with the boiler by pipes 8, 31, 28, 30, and27, and the height of the water within the boiler can be observed fromthe water-gage 26, also from the water-glass 12, carried by the tank 5.The capacity of the tank 5 is made such that when the water accumulateswithin the tank the weight of the same will lower the tank 5, andthrough the medium of the screwstem 2 L, lever 21, and valve 16 the flowof water through the pipe 14 to the boiler will be regulated. Thereceding movement of the tank 5 compresses the spring 9, and upon thewater again assuming its level the spring expands and raises the tank 5.The tension of the spring beneath the tank 5 can be regulated by theset-screws 11 11, carried by the platform 4:. The operation of the valve16 can be adjusted by the nuts 23 28, carried by the screw-threaded stem24:.

a On account of the vertical movement of the tank 5 we have found itnecessary to employ a swiveledconnection 29 to permit of the pipe 8being moved without distorting or moving the stationary connections ofour improved device, and the swiveled connection 29 can be readilyemployed in connection with the other pipes where one pipe moves inrelation to another pipe.

From the foregoing description,.taken in connection with the drawings,it Will be observed that the quantity of water fed to the boiler can bereadily controlled by our improved regulator, and while we have hereinillustrated the same as being mounted upon the front of the boiler itcan be readily secured to a suitable support located in the vicinity ofthe boiler, and it is always essential that it be elevated at a heightcorresponding to the water-line of the boiler.

It is obvious that various other changes may be made in the details ofconstruction without departing from the general spirit and scope of theinvention.

What we claim, and desire to secure by Let ters Patent, is-

In a device of the type described, the combination with a boiler, aframe mounted adjacent to the boiler, a tank movably mounted in saidframe, a spring arranged below said tank, means carried by said framebelow said spring to regulate the resiliency of the spring, aninlet-pipe leading from the boiler to said tank, an outlet-pipe leadingfrom said tank to the boiler, a supply-pipe leading to the boiler, avalve arranged on said supply-pipe, a pivoted lever attached to saidsupply-pipe and adjustably connected to said tank, substantially asdescribed.

In testimony whereof we afiix our signatures in the presence of twowitnesses.
